Abstract

PURPOSE:To eliminate the effect due to temperature fluctuation, by carrying out limiter operation through the provision of a diode between the input and output of a differential amplifier. CONSTITUTION:An input signal voltage VO is given to an inverting input terminal of a differential amplifier 20. When the voltage VO is smaller than a reference voltage Vref given to a noninverting input terminal, an output K times the difference between the Vref and the VO appears at an output terminal voltage 26. In this case, since a voltage inverse to a diode 23 is applied, the voltage VO receives no effect. When VO>Vref, the diode 23 is conductive by the output of the differential amplifier 20 and the differential amplifier absorbs excess current, allowing to limit the amplitude of the input signal.
